Patented Mar. 26, 1935 UNITED STATES PATENT OFFICE 1,995,374 DENTIFRICEHOLDING TOOTHBRUSH James D. Young, Sierra. Madre, Calif. ApplicationApril 23, 1934, Serial No. 721,887

1 Claim. (01. 1s7) dentifrice holding 5 dentifrice pellet.

A more specific object of the invention is to provide a tooth brushincluding bristles where-.

in a portion of the bristles are arranged to form a pocket for thereception of a pellet of dentifrice.

Another object of my invention is to provide a novel dentifrice pellet.

Other objects of the invention will be apparent from the followingdescription taken in connection with the accompanying drawing, wherein:

Fig.1 is a side elevation partly in section, showing my improved toothbrushes;

Fig. 2 is a section taken on line 2-2 of Fig. 1;

Fig. 3 is a central sectional view through one of my pellets;

Fig. 4 is a fragmentary sectional view, showing my novel dispensingcontainer for the pellets;

Fig. 5 is a fragmentary bottom plan view of the end of the container;

Fig. 6-is a section taken on line 6-6 of Fig. 4;

Fig. 7 is a fragmentary top plan view'showing a modification of my toothbrush;

Fig. 8 is a section taken on line 88 of Fig. '7;

Fig. 9 is a section taken on line 9-9 of Fig. 8;

Fig. 10 is a front end view of a further modifled brush; and,

Fig. 11 is a section taken on line 11-11 of F18. 10.

Referring to the drawing by reference characters, I have illustrated myinvention in a tooth brush which is indicated generally at 10. As shown,this brush includes a head 11 and a handle 12. The head is provided witha'plurality of bristle tufts 13, which are arranged preferably inlongitudinal and transverse parallel rows. The tufts may be secured inthe head in any desired manner, as by vulcanizing, and the free ends ofthe bristles may have their brushing surface arranged in any desiredconfiguration.

At a desired location I arrange certain of the adjacent tufts with theirends shorter than the ends of the surrounding tufts, as indicated at 14,in Fig. 2. This arrangement provides a pocket 15 for the reception-of apellet of dentifrice which is indicated generally at 16. This pelletcomprises a central or core portion 17 which may be a powder or whichmay be plastic in the nature of a cream and a covering 18 which may bemade of such material as starch, or any material having the desiredinert or other properties and which is soluble in water.

In Fig. 4 I show a container at 19 which is 5 adapted to hold dentifricepellets. This container has a neck 20 thereon and is provided with anaperture 21 in the neck. From the wall of this aperture a plurality oftongues 22 (see Fig. 5) extend inwardly. These tongues are of a size 10to engage a pellet 16 and prevent the latter from passing through theaperture 21. An ejector 23 is preferably made of resilient material andincludes an operating end 24.

In use the tooth brush 10 is placed with the 15 pocket 15 arrangedbeneath the aperture 21. The portion 24 is then depressed and one end ofthe pellets passes through the aperture 21 into the pocket 15. The brushis then moistened and is used in the usual manner.

In Figs. 7, 8 and 9 I show a modification of my invention wherein thebrush indicated generally at 25 is provided with a hole 26 through thehead thereof. The brush is provided with the usual bristles 27. Thesebristles are omitted ad- 25 jacent the hole 26 to form a pocket 28. Thebristles are resilient and thus when a pellet is passed through the hole26 it is engaged and retained by the bristles as shown in Figs. 8 and 9.

In Figs. 10 and 11, the brush 30 is provided 0 with bristles 31. Thesebristles in the center of the brush at one end are omitted thus forminga pocket 32 in which the pellet 16 will be retained in place by theresiliency of the bristles.

From the foregoing description it will be ap- 5 parent that I haveinvented a novel dentifrice holding tooth brush which is simple inoperation and which can be very economically manufactured and which isalso very efiicient in use.

Having thus described my invention, I claim: 40

In a tooth brush, a body having a handle thereon, a plurality of tuftsof bristles arranged in the body, said tufts being disposed in parallel,longitudinal and transverse rows, the lengths of the bristles in certaintufts in one portion of the brush being of substantially one-half thelength of all of the surrounding tufts of bristles to provide a pocketadapted to receive a pellet of dentifrice with the said tufts'ofbristles which surround the shorter tufts being adapted to engage thepel- 50 let and. hold it in position.
